SAFETY ZOB.

Application led March 31, 1925. Serial No. 19,583.

To/LZZ whom t may concern: Be it known that l, lnviNG SMITra, a citizenof the United States, and a resident of Winsted, county of Litchfield,and State of Connecticut, have invented certain new and use fulImprovements in Safety Razors, of which the following is aspecification.

This invention relates to razors, and more particularly to a safetyrazor having a thm fla-t handle arranged obliquely to the edge of theblade so that the correct diagonal shaving stroke will be easilyobtained by the user. The object of this invention is .to provide adevice of the above nature which will be simple in construction,inexpensive to manu; facture, easy vto manipulate, ornamental inappearance, and very efficient and durable 1n use.

`With these and 'other objects in view there have been illustrated -onthe acompanymg drawings, several forms in which the invention may beconveniently embodied in practice.

Figs. 13 and 14 are top views of two modifiedwforms of razor blade.

Fig. 15 is a top View of a modified form of guard member adapted forruse withany of the above-illustrated forms of safety razor.

Fig. lfiwis a side sectional view of the same,

taken along the line.1616 of Fig. 15.A

Fig. 17 is a top view of another modified form ofv guard member.

Figs. 18 and 19 are-top and end views respectively of a modified form ofclamping plate to be used with the guard member shown infFigs. 15 and16.v

Referring now to the drawings in which like reference numerals denotecorresponding parts throughout the several` views, theinumeral 20, Figs.1 and 2, indicates a clamping plate for a razor blade 27, said clampingplate and razor blade `being in the form of oblique parallelograms. Theclamping plate has curved upper and lower faces, and is provided with apair of end pins 21 and 22 and a central upstanding tapped post 23.

"The postl 23 has an enlarged base' section 24 with parallel Hat sidefaces, and above said base sectionl24f the post 23 has a reduced sectionwith flat side faces 25 and 26, said faces y being parallelto the endsof the clamping plate 20.l

The razor blade 27 has a pair of end 'apen 28 which has rows of teeth 29and 30 on its opposite sides.

'clamping plate 20 and blade 27 and is held against said blade by meansof a screw rod 31 passing through the interior of 'a handle 32. i

fiat parallel opposite side faces 35 and 36,

The guard member 28 hasv the same oblique parallelogram shape as theandis non-rotatively held at an oblique angle to the sides ofthe bladeand parallel to the ends of said blade, said angle being such that inshaving, it will be easy for the user .toobtain the correct diagonalstroke across tures adapted to lit. over ,the pins 21 and a l centralaperture to )surround'the post 23, said blade being covered by a guardmember the face. The inner end of the handle 32 is pravided with a'slot37 having curved ends and at sides and adapted to fit over ,the ends andsides of the post 23.

By means of this construct-ion, when the screw rod 31 is screwed intothe post 23, the handle member 32 will be forced down upon 'the guardmember 28, which .in turn will press the blade 27 upon the clampingplate 20.

In Figs. 5 to 9 a. modified second form of the invention is illustrated.This form of safety razor comprises a clamping plate 38 havingy the sameoblique parallelogram shape as in the first form, and having end pins 39and 40 identical with the pins 21 and 22 of the first form. The clampingplate 38 is provided with an upstanding post 41 threaded on its exteriorat 42v and having a reduced tongue 43 at its top portion, said tonguehavingfiat sides 44 and 45 parallel to the ends of said clamping A guardmember 46 anda blade 47, which are identical with the guard member 28and blade 27 of the first form of razor shown in Figs. 1 to 4, areadapted to be held upon the clamping plate 38 by means of a swivelcollar 48, as most clearly shown in Figs. 6 and 9. The swivel collar 48is preferably knurled on its exterior and has an inwardly directed lug49 at its top adapted to fit loosely within an annular slot 50 in a flathandle member 51, said handle member 51 having fiat sides 52 and 53parallel to the ends of the clamping plate, as in the first illustratedform of 'the invention.

.In order to hold the handle rigidly in its correct angular Jositionwith respect to the blade, the hand e 51 is provided with a slot 54adapted to fit snugly over the fiat tongue 43 of the bed post.

A still further modified third form of the invention is shown lin Fi 10.This form of razor is identical ywit the forms shown in Figs. 5 to 9,except that the bottom of the handle is provided with a flat tongue 55and the center post of the clamping plate is provided with a slot 56fitting over said tongue 55 for holding the handle 57 at the correctoblique position.

In Figs. 11 to 14, three modified forms of razor blade are illustrated.In each form, the blade is in the shape of an oblique parallelogramcorrespondingto the shape of the clamping plate as shown in Figs. 3 and7.

In the Iform shown in Fig. 11,' the blade is provided Vwith a pair ofend apertures 58 and 59 for fitting over the end `pins of the clampingplates, and said blade has a central aperture 60, the latter having theshape of an oblique parallelogram with its sides parallel tothe ends ofthe blade. The central aperture is adapted .to fit snugly `guard memberis shown.

over the center osts of any one of the is provided ywith a cross shapedhole 61, the ends of which communicate with central side -arms 62 and 63thereof.

The form of blade shown inFig. 14 is identical tothat shown`in Fig. 11except that the central post aperture 64 is made 1n the shape of anellipse.

In- Figs. 15 and 16 a modified form of In this form of' guard member, apair of longitudinal ribs 65 and 66 are struck up from the base of.

the guard member to provide a pair of grooves to fit over a pair of ribs67 and 68 extendmg outl from each side of a tapped .post 69 whichprojects up from a clamping plate70, as clearly shown in Figs. 15',

18, and 19. It will be understood that the modified forms of gua-rdmember and clamping plate shown in Figs. 15, 18, and 19 may be employedinterchangeably in any of the three illustrated forms of razor.

In Fig. 17 a still further modified form of guard member 71 isillustrated. This form of guard member has a cross-shaped hole 72similar to the hole 6110i?. the blade shown in Fig. 13.

The guard member 71 is especially adapt-4 ed for use with the clampingplate 70 shown ,in Fig. 18, but it may also be used with the otherillustrated forms of clamping plate within the general spirit and scopeof the invention.

While there 4have been disclosed in this specification several forms inwhich the invention may be embodied, it is to be understood that theseforms are shown for the purpose of illustration only, and that theinvention is 'not to be limited to the specific disclosures 4but may bemodified and embodied in various other forms'without departing from itsspirit. In short, the in# venti'on includes all the modifications andembodiments coming within the scope of the following claims.
